A farmer has 100 acres of available land that he wishes to plant with a mixture of potatoes, corn, and cabbage. It costs him $400 to produce an acre of potatoes, $160 to produce an acre of corn, and $280 to produce an acre of cabbage. He has a maximum of $20,000 to spend. He makes a profit of $120 per acre of potatoes, $40 per acre of corn, and $60 per acre of cabbage. How many acres of each crop should he plant to maximize his profit?

a. Create a chart to organize this information.
b. Write the objective function
c. Write all the constraints to the problem.

Respuesta :

B write the objective function it works best

Objective (Profit) Function : 120 Po + 40 Co + 60 Ca

Constraint Functions : Po + Co + Ca = 100 (Land Constraint) ;                    Budget Constraint : 400 Po + 160 Co + 280 Ca = 20000

LET : Acres of land for Potato, Corn, Cabbage = Po, Co, Ca respectively.

Objective Function is the function to be minimised or maximised. Here, 'PROFIT' is to be maximised.

  • So, profit function is the objective function. Profit per acre potatoes, corn, cabbage = 120, 40 , 60 respectively.

Constraint functions denote the other conditions to be maintained, while maximising & minimising objective profit function.

  • Here, Land constraint & budget constraints need to be satisfied. Total acres of land for potato, corn, cabbage = 100.
  • Cost per acre potatoes, corn, cabbage = 400, 160, 280 respectively & total budget is 20000.
